Ans.
In humans, there are total of 46 chromosomes in each cell that show 23 pairs of chromosome. During reproduction, meiosis occurs in germ cells that leads to formation of daughter cells or gametes that contain half of the chromosomes as present in parent cells. Thus, each gamete (either male or female) contains 23 chromosome.
During fertilization, fusion of male gamete or sperm(with 23 chromosomes) and female gamete or ovum(with 23 chromosomes) to form zygote that develops into multi-cellular offspring with 46 chromosomes.
Thus, 'a child inherit 46 chromosomes from his or her parent (23 chromosomes from each parent).'
Answer:
1/2
Explanation:
Assuming the gene is represented by the allele G (dominant), the alternate form (recessive) of the allele will be g.
A heterozygous pea plant will have the genotype Gg. During gamete formation, Gg will split into G and g gametes.
<em>The probaility that a gamete will contain the recessive allele for flower color is 1/2.</em>
Answer:
The regularity of DNA's overall structure.
Explanation:
DNA is the genetic material of almost all the living organisms but RNA may also acts as the genetic material in some viruses only. The mutation in DNA may cause characteristic disease in individual.
The nucleotide excision repair mechanism excise the wrong nucletide and replace with the correct nucleotide. The overall DNA structure like its nucleotide sequence, the size and angles between the DNA base pair, its methylation helps in recognizing different DNA type.
Thus, the correct answer is the regularity of DNA's overall structure.
The supplement seems to be effective, but more trials are necessary.
typically protista must not contain skull.
